best. cat. toy. EVAR. [youtube] →[More:]
Not my cat(s) but we have a hexbug nano; that exact model/colour in fact. Marlowe has grown so attached to it that when he wants to play, he grabs it from wherever we've stashed it and bring it to us so we'll turn it on for him to play with. It's an amazingly simple, agile and durable toy, the batteries last quite a while, and it will even flip itself over if it lands on its back.
the only downside is that it's so small and quiet that we have to keep an eye on where it goes so that it doesn't end up stuck way back under the futon or hidden in a pile of laundry somewhere.
We will have to shoot video of Marlowe playing with our hexbug. In the meantime, here are a couple of quick live-action Marlowe vids for you. They're not the best ever, but they show the, um, rather inventive redecoration of our living room that the mister has done to entertain our fuzzball :)
